To all whom it may concern:

Be it known that I, OnnANno H. BROWN, a citizen of the Dominion of canada resid ing at Victoria, in the county of Victoria and Province of British Columbia, have in.- vented certain new and useful Improvements in Grain Elevators, of which the following is a specification. V g y The present invention relates to improve.- ments in grain elevators and the principal object is to providea device ogfthe character set forth, which is adapted for connection to grain carrying vehicles, whereby the grain may be conveyed or elevated into the storageelevator or grain ear.

A further object of the invention is jtO provide a grain conveyor the elevating mechanism ,of which is automatically ,operable and which isso constructed as to be readily. transferred from place toiplace. Another object of the invention is to provide, suitable knockdown supporting means for the elevator.1

W'ith these and other objects in view, the

invention consists in the construction,- combination and arrangement of parts as will be hereinafter fully described, illustrated in tlieaccompanying drawings, and pointed out in the claims hereunto appended. Figure is detail elevational view of the improved elevator, illustrating the application of the same to a vehicle and storage elevator. A h Fig. 2 is a longitudinal section through the 'elevator. v

Y f Fig. 4% is a fragmental magnified elevation of the upper end of the elevator, witha part of the outer: casing removed.

Fig. 11 is a section on line 1010 of Fig. 10.

Fig. 12 is a fragmental cross sectional view of the vehicle bed, to which the elevator is attached; and

Fig.13 is a'detail view of the adjusting rod for the vehicle hopper regulating plate.

Referring to the drawings, like numerals designate like parts in the various drawings. In the transportation of grain from the field to the storage elevator, or to the railway cars, heretofore difficulty has been 6X- perienced in transferring the grain from the vehicle to the depository elevator,owing to the time and labor involved. With the obviation of these objections inview, I have provided ana'pparatus adapted for continuous actuation, to convey the grain from the vehicle to the storage depository, without the recourse of shovelling.

The apparatus comprises preferably a rectangular casing 5, formed of wood or sheet metal, having an upwardly directed spout 6 connected to the lower end and a downwardly directed spout 7 connected to the upper end. "Shafts 8 and 9 are mounted in suitable journals 10 in the upper and lower ends of casing 5. Sprocket wheels 11 and 12 are keyed upon shafts 8 and 9 and revolve therewith. A series ot brackets 13 areriveted to the side wallsl i'ot the casing Sand connected to said brackets 13 are the guide rails 15. A; chain 16 is trained'around sprocket wheels 11 and 12. and comprises a continuous series of alternately disposed links 17 and 18 connected together by pins 19, Eachalternate link 17 is formed centrally with a rectangular opening 20 which is adapted to engage over-the teeth 21 of sprocket wheels 11 and 12. Links 18 comprise spaced side bars 22 to which are. connected by rivets 23, the brackets 24.

Connected to the chain'brackets 24am the bucket units 25 and 26. the former having closed ends27, while their open ends are adapted for the reception of the open end portions of thebuckets 26. The last mentioned buckets 26 are formed 'at one end with oppositely disposed semi-circular flanges 28, which are apertured for the pins 29, by means of which the hollowbucket units 26 are hingedlyconnected to the bucket units 25. A portionSO of the base of each bucket 26 projects within the open ends of the buckets 25, so that th two buckets 25 and 26 together form transversely extending rectangular bucket units connected, as stated, to each alternate link 17 and spanning each drive link 18.

Mounted on the end of shaft 8, which projects beyond one of the side walls 14- of easing 5, is a gear- 31 and likewise journalled in the side wall 14, is a pin shaft 32. A

sprocket wheel 33 is keyed to the outer end of the pin shaft 32 and a. chain 34 is trained over sprocket wheel 33 and, gear 31. A crank is connected to the outer end of shaft 32 and has an operating handle mounted thereon.

Theelevator casing 5 is supported in in.

- 44, secured to the lower surface of easing 5 and serve to hold the casing upon the support. Wire pull members 45 areattached to the inner ends of the latchfpins 42 and when pulled withdraw the pins 42 from within the openings in the studs 44, to release the support 36 from casing The lower spent 6 is hingedly connected to the lower end ofcasing 5 and hassuitable connecting elements 46 secured'thereto, the opposite ends being attached to the casing 5. While the greater part of the lower spout 6 is directed at an angle to the casing proper, the upper end extends substantially in vertical plane. This spout 6is adapted for 211'.- rangement in alinement with the outlet opening in the base of vehicles engaged in the transportation. of grain. In this instance,,vehicle 47 is provided with a base opening in which is mounted a downwardly extending tubular extension 48. The lower open end'of extension is normally closed by aplate 49 to which is connected the inner end of a bar or lever 50, by means of which Y the plate 49 is adjusted to allowthe grain contained in the vehicle to pour through and into the spout 6. The grain which pours through spout 6 gravitates downwardly and occupies the space 51 at the lower end of the spout and is subject to the shoveling action of. the buckets.

In operation, crank 35 is manually actuated and imparts motion through sprocket wheel33, chain 34 and sprocket 31 to the elevator chain belt.

As the elevator beltis actuated, the buckets travelling inthe direction of the arrow in Fig.2, scoop up the grain accumulated in the space 51. This grain is conveyed upwardly in the buckets and deposited into the spout 7 and passes through the spout 52 leading into the storage elevator By the pivotal connection ofthe bucket units, the same are enabled to pass freely around the sprocket wheels 11 and 12 and likewise a relatively large amount of grain can be carried by the said buckets.

It is possible that with several slight modifications, to adapt this elevator to convey grain from the railway box cars or the ordinary grain cars. In this instance the spout 6 would be disconnected and the end of easing run through the car door opening,

From the foregoing,it is thought that the construction of my invention will be clearly understood, and, therefore, a more'extended explanation has been omitted.

Having thus described my invention, what I claim as new, is:

' 1. In an apparatus for elevating grain from wagons, the combination'with a casing and rotatably mounted shafts arranged therein, of gears mounted on said shafts, a chain actuated by said gears, means for guiding and supporting the upper flight of said chain, a plurality of bucket sections pivoted to each other and secured to alternate links of said chains and operable therewith, means for connecting said casing to the wagon and means for actuating said chain. 7 a V 2.
